DOUGLAS CAMPBELL JAMIESON, OF WEST KILDO'NAN', AND FREDERICK ROW'ETT, OF WINNIPEG, MANITOBA, CANADA.

DEVICE FOR ATTACHING WINDOW SCREENS.

Application filed May 10,

To all whom it may concern:

Be it known that we, DOUGLAS C. Janna- SON and FREDERICK Rown'r'r, citizens of Canada. and residents, respectively, of lVest Kildonan, Province of Manitoba, Dominion of Canada, and lVinnipeg, Province of Pilanitobm'Dominion of Canada, have invented a new and Improved Device for Attaching lVindow Screens, of which the following is a description.

Our invention relates to a device for securing the frame of a window screen to the window frame and has for its general object to provide a device for the indicated purpose of extreme simplicity and of such a character as to permit of its being firmly secured to the window frame with facility.

The nature of the invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Re Terence is to be had to the accompanying drawings forming a part of this specification, it being understood thatthe drawings are merely illustrative of one example of the invention.

Figure 1 is a perspective view showing our improved screen securing means applied to a screen and to a window frame shown in part;

Figure 2 is a horizontal section through the securing device, window frame parts, and screen;

Figure 3 is a plan view of the securing device;

Figure 1 is a transverse vertical section taken through the slotted arm of the securing device.

In the illustrated example the letter A indicates a portion of a window frame; 13, the outside stop on the window frame at the jamb; C, a vertical member of a screen frame; and D, the screen mesh.

Our improved securing device consists of a strip of flat metal designated generally by the numeral 10 and bent to form a comparatively long end arm 11 adapted to lie against the inner face of the screen frame member C. The strip 10 is bent generally into Z- form and in addition to the arm 11 has an intermediate portion 12 at right angles to the arm 11 to lie against the side face of the stop B while at the end opposite the arm 1924. Serial No. 712,344.

11 the strip 10 is bent again at right angles to form the terminal member 18 at right angles to the member 12 and to lie against the inner face of the stop B. The arm 11 is the securing member of the strip 10 and said arm has a slot 14 therein adapted to receive a fastening screw 15, which engages the bevelled side edges of the slots let to lie flush with the arm 11 and to engage tightly by its head against the arm 11 for holding the device firmly to the screen frame member C.

As clearly seen in Figures 2 and 3, the terminal arm 13 that lies against the edge of the stop B has its end 16 deflected outwardly that is to say, toward the plane of the screen frame arm 11 which will impart a certain amount of elasticity, the purpose of which 7 formation is to cause the end of the arm 13 to ride over and embed itself in the ma.- terial of the stop 13 to an extent to aid in holding the securing strip 10 against vertical displacement or possible turning about 7 the screw 15 as an axis. In applying the securing strip 10 to the frame member 0 and stop 13, the deflected end 16 will contact with the rear face of the stop adjacent to the plane of the jamb and as the screw 15 30 draws the arm 11 flat against the frame memher C. the end 16 through its elasticity read ily embeds itself in the stop B.

We would state in conclusion that while the illustrated example constitutes a pracs5 tical embodiment of the invention, we do not limit ourselves strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Having thus described our ii'lvcntion, we claim:

As an article of manufacture, a device for attaching window screens, the same consisting of a strip bent generally into Z-form presenting a long arm at one end adapted to lie against a screen frame member, said arm having a slot therein to receive a fastening screw, the intermediate portion of the said strip being at right angles to said arm and of a length to lie against the face of a stop head on a window frame, the end opposite said frame being in the form of a second arm at right angles to the intermediate portion frame when the fastener tightens the first and disposed oppositely to the first arm, saidi arm against the screen frame, to prevent second-mentioned arm adapted to lie against vertical movement of the screen, and tnrn- 10 the inner edge of the Window stop and having of the device upon its fastening screw. ing its end deflected toward the plane of the first arm to embed itself in the material of DOUGLAS CAMPBELL JAMIESON.
